Default [Help Needed] Sony CDP-S37/S207 schematic

Dear all,
this is my first posting. and I really need everyone help if anyone have this Sony CDP-S37 schematic. I have been searching around and found none.
This CDP was low end CDP with Sanyo LC9600 DAC and KSS211A optic.
Yes indeed that Sanyo LC9600 and KSS211A is not a common part (only 2 types of sony CDP use this combination, S37 & S207) and that is why I really need the schematic.
Anyone can suggest me easy tweak for this CDP ? I planned view things :
1. change all caps in PSU section from Elna RE2 into Cerafine or Silmic II
2. change caps on analog section from elco into MKP but this is the part that I need the schematic.

any advice & comment would really appreciated.

Thank you

Yuda

The most cost effective upgrade to cheap CD players is the opamps used for I/V conversion and output filter/buffer. I'm not familiar with your player, but I would look at opamps first, perhaps also replace PSU electroylitics with good quality parts.

@mooly : thanks for the suggestion. I will do the replacement for the PSU unit. and also thinking to replace the op-amp. but i am not sure about it (the exact IC for the I/V conversion), that is why I need the schematic. but thanks anyway.
